This NU145 Unit 5 observation paper keeps a running record of a composite boy of about 30 months in a public library's toddler corner who spends forty-five minutes building beside another boy without ever building with him. It belongs to Purdue Global NU 145, Psychology Across the Lifespan, a BSN course. The record uses plain verbs in timed entries every five minutes. The interpretation then sorts each entry into physical, cognitive, language or social development and compares it with what the 2022 CDC checklists expect near two and a half. Parallel play is counted rather than simply named, inferences are labeled as inferences, and the paper considers what the observer's presence may have changed.

Unit 5 Observation Paper

[Instructor Name]

[Date]

The child and setting are composite and written as a model; a real observation requires the permissions and rules the student's course sets, and those records stay with the student.

What this part is doingThe record and the interpretation are kept in separate sections, which is the discipline an observation paper is graded on.
2

Setting and Method

The observation took place in the toddler corner of a public library on a [weekday] morning from 10:00 to 10:45. The writer sat on a bench about three meters away, did not interact with the children and recorded at five-minute intervals. The child, called C. here, is identified only by approximate age, [30] months, and sex. Any real observation, its permissions and its notes rest with the student who carries it out. A running record writes down what the child does and says in the order it happens, using observable verbs, and saves interpretation for later (Bentzen, 2009).

Running Record

10:00 C. sits on the mat. Picks up a red block. Stacks four blocks. Looks at a boy, about the same age, stacking blocks one arm's length away. 10:05 Knocks his stack down. Laughs. Says "Boom!" Restacks five blocks. 10:10 Picks up a toy truck. Pushes it along the mat. Says "Truck go." Drives it to the other boy's stack. Stops. Drives it back. 10:15 Walks to the bookshelf. Climbs onto a low step and down again. Returns to the mat. 10:20 Holds out a block toward the other boy. Pulls it back. Adds it to his own stack. 10:25 Other boy takes a block from C.'s pile. C. says "Mine!" Takes it back. Other boy turns away. 10:30 Builds a row of six blocks. Pushes the truck along the row. Says "Big road. My road." 10:35 Looks at the other boy's tower for about ten seconds. Builds a tower of his own next to it. 10:40 Caregiver says it is time to go. C. says "No, more." Stacks two more blocks. Takes caregiver's hand. 10:45 Walks out, holding hand, carrying the truck until caregiver takes it back to the shelf.

What this part is doingThe record uses plain verbs only, "stacks," "looks," "says," so a reader can check every later interpretation against it.

Interpretation by Domain

Physical. C. stacks five to six blocks, walks steadily, climbs a low step and comes down without help. These fit what most children do by 30 months; the CDC checklists, revised in 2022, list skills such as taking some clothes off and jumping off the ground with both feet near this age, and set each milestone at an age most children have reached (Zubler et al., 2022). Stacking and steady climbing are consistent with typical motor development. Cognitive. Lining blocks into a "road" for the truck is simple symbolic play: one object stands for another. Knocking down a stack and rebuilding it to laugh again shows cause-and-effect play still in use. Language. C. uses one- and two-word phrases and one three-word phrase, "Big road. My road." The 2022 checklists expect a child of about 30 months to say about 50 words and to combine two or more words including an action word, such as "Truck go" (Zubler et al., 2022). C.'s speech fits that description. Social. C. watches the other boy, builds beside him, copies his tower and once almost offers a block, but the two never play together toward a shared goal. Parten's classic categories call this parallel play: children playing near each other with similar materials but not together (Parten, 1932). His "Mine!" when a block is taken is ordinary for this age.

Ten minutes of entries showed the same pattern six times: watch, come close, build alongside, never build together.

What this part is doingParallel play is shown by counting entries, not just named, which makes the interpretation verifiable.

Inference Labeled as Inference

Some statements go beyond what was seen. That C. "almost offered" a block at 10:20 is an inference from a single held-out hand; he may simply have been looking at it. That parallel play is typical for him is an inference from forty-five minutes on one morning; his play with familiar children may be more cooperative.

What the Observer May Have Changed

An adult sitting nearby, writing, may have made C. or his caregiver more careful. The library setting, with unfamiliar children, may also favor parallel over cooperative play. Repeating the observation in a familiar setting, such as child care, would test whether the pattern holds.

Conclusion

In this observation, C.'s motor, language and social behavior fit what most children show near two and a half, with parallel play as the clearest pattern. One forty-five-minute record can describe a morning; it cannot assess a child. Its value is in showing how careful recording makes later interpretation honest.

Appendix: Raw Notes as Taken

C. ~2.5 y M. 10:00 sits, red block, stack 4, looks at boy. 10:05 knock, laughs, "boom," restack 5. 10:10 truck, "truck go," to boy's stack, back. 10:15 shelf, step up/down. 10:20 holds block out, pulls back. 10:25 boy takes block, "mine," takes back. 10:30 row 6, truck, "big road my road." 10:35 looks at tower ~10 s, builds own. 10:40 "no more," 2 blocks, hand. 10:45 out w/ truck, returned.

The Purdue Global NU145 Unit 5 instructions

Unit 5 usually asks students to observe a child, often a toddler or preschooler, in a public setting and write up what they saw. Prompts commonly require a description of the setting and method, an objective running record, an interpretation linking behaviors to developmental domains and theories, and reflection on the limits of a single observation. Instructors look for records that describe actions without judgment, interpretations that can be checked against the record, accurate milestone comparisons and respect for privacy, with the child identified only by age and sex. Programs set rules about permission and setting. Expect four or five pages, supported by an observation methods text, a milestone source and a theorist cited in APA 7.

Inside the NU145 Unit 5 example

The paper opens with the setting and method, the distance kept and the privacy rule, citing an observation methods guide. The running record lists ten timed entries in plain verbs, with a margin note on why. The interpretation section takes each domain in turn: motor skills, symbolic play, two-word phrases checked against the CDC checklists, and parallel play named with Parten's categories. A highlighted line counts the repeated pattern. A section separates two inferences from what was seen, another considers the observer's effect and suggests a second observation in a familiar setting, and the conclusion states what one morning can and cannot show. The raw notes appear in an appendix.

NU145 Unit 5 rubric: what earns full points

Observation paper rubrics in NU 145 commonly award points for objectivity of the record, accuracy of interpretation, use of developmental sources, reflection on limits, ethics and writing. Objectivity points depend on entries that describe actions rather than feelings or judgments. Interpretation points reward links from specific entries to specific domains and milestones. Source points go to a current milestone reference and a correctly applied theory such as Parten's play categories. Reflection points are earned by naming inferences and the observer's possible influence. Ethics points require the child identified only by age and sex. Writing points cover organization, timed entries and an appendix of raw notes. Counted patterns tend to score higher than impressions.

NU145 Unit 5 help: mistakes that cost points

Observation papers commonly lose points when the running record includes judgments, such as "he was shy" or "he wanted to play," which belong in the interpretation. Another frequent error is comparing a child with milestone ages from an outdated chart. Some students name a play type without showing the entries that support it. Others draw conclusions about a child's development from one short visit. Write the record in verbs only, keep interpretation in its own section, cite a current milestone source, show the entries behind each claim, label every inference and note how your presence and the setting may have shaped what you saw. Follow your program's rules on permission.

Where can I find a free NU145 Unit 5 sample paper?

This page holds the complete NU145 Unit 5 observation paper on a composite toddler in a library play corner, with a running record, interpretation by domain, limits, raw notes and three sources. We can help you organize notes from your own observation into this form.

What is a running record?

A written account of what a child does and says, in order and with times, using observable verbs. Interpretation is saved for a separate section so it can be checked against the record.

What is parallel play?

Children playing near each other with similar materials but not together toward a shared goal. Parten described it as a common form of play in toddlers.

What words should a 30-month-old use in NU145 Unit 5 terms?

The 2022 CDC checklists expect about 50 words and two or more words combined with an action word, such as truck go, near 30 months.

Can one observation assess a child's development?

No. One session describes a morning in one setting. Repeating the observation in a familiar place would show whether the pattern holds.
